For the flesh sets its desire against the Spirit, and the Spirit against the flesh; for these are in opposition to one another, so that you may not do the things that you please. - GALATIANS 5:17
Cows may have two stomachs, but I’ve never heard of an animal with hearts on each side of the chest. That would be a mutant. Yet there are people who try to operate with two spiritual hearts. One attempts to be set on God, and the other on the world. They haven’t learned the principle that being the ally of the world’s values makes them automatically the enemy of God. (JAMES 4:4)
The two spiritual hearts are like trains, one heading east and the other west. A train wreck is inevitable. The answer is to get one train on one track, one heart guided by one passion. If you hop on the train of the flesh, you will lose your spiritual energy. But if you opt for the spirit, you will have vitality from inside that fuels the flesh for doing good things.
Avoid the train wreck. Recognize that if the flesh-focused heart wins you still have a mess. Go with the heart alive with God’s Spirit.
Nourish the spiritual heart and it will overcome the flesh-focused heart.
